GAS-BURNER.

Specification of Letters Patent.

Patented Feb. 15, 1910.

Application filed January 20, 1909. Serial No. 473,224.

lowing to be a full, clear, and exact descrip' tion of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to new and useful improvements in gas burners, and particularly to gas burners of the inverted type.

One of the maiii objects of this invention is the provision of a gas burner having a construction such that the gas will be supplied to all parts of the mantle, with the result that the entire mantle will glow with intense luminosity and the lamp will have an efiiciency greater than those in use at the present time.

A further object is the provision of a burner having its parts, particularly those subjected to intense heat, so assembled and supported or united that the heat of the lamp cannot have any material detrimental effect on the lamp.

A still further object is the provision of a burner having a construction such that all the parts can be easily and quickly assembled or taken apart whennecessary.

Further objects will appear from the following detailed description.

The invention may be briefly summarized as consisting in certain novel details of construction and combinations and arrangements of parts which will be described in the specification and set forth in the appended claims.

In the accompanying drawings, Figure 1 is a vertical sectional view taken through a burner constructed in accordance with my invention. Fig. 2 is a section taken through the mantle, the section being taken substantially along the line 2-2, Fig. 1, looking in the direction indicated by the arrow. Fig. 3 shows in side elevation the lower part of the vertical lamp-supporting and gas-supplying tube and the funnel-shaped member at the lower end of the tube forming the flaring orifice, and showing also the shape of the slots in the conical portion of this member for receiving and supporting the mantle-supporting frame. Fig. 4 shows in elevation the funnelshaped locking sleeve which fits over the funnel-shaped member at the lower end of the tube of the burner and locks the mantle supporting frame in position.

Referring now to the figures of the draw ings, 10 represents the vertical burner-supporting and gas-supplying tube which is provided at one end, which in the present case is the upper end, since I have shown my invention applied to a lamp of the inverted type, with a gas regulating valve 11 having a tubular projection 12 which may be connected to a gas fixture in. any suitable manner, the tube being also provided near the lower end of the valve with air inlet openings 13. At its lower end the tube is provided with a flaring orifice which is preferably formed by a separate funnel-shaped member 14 having a cylindrical portion 15 which surrounds the lower end of the tube, and an outwardly flaring or conical portion 16 below the end of the tube. This funnel shaped member 141: is preferably secured to the tube by a transverse pin 17 which extends through diametrically opposite openings in the cylindrical portion 15 so that the pin will extend across the tube centrally thereof. This in 17, aside from uniting the tube 10 and funnel-shaped sleeve 14, per forms an important function to be described later. The ends of the pin are preferably flush with the outer surface of the cylindrical portion 15 of the member 14: or at least do not extend beyond the outer surface of this member, and the pin may be fixed in position, or may be loose as desired, so that the two members united by the pin can be readily taken apart.

Near the bottom of the conical portion 16 of the member 14 are a number of bayonetshaped slots 18 which extend upwardly from the bottom and thence laterally so as to form shoulders 19 for supporting the mantleframe. The mantle which is shown at 20 is secured in any suitable manner to a frame comprising a ring 21 having inwardly extending lugs or projections 22 spaced equal distances apart, the lugs being, in this case, three in number. These lugs are of a width such that they may be slipped upwardly into the slots 18 and when the frame is turned slightly, will pass into the laterally extending portions of the slots and will rest upon the shoulders 19.

Surrounding the funnel shaped member 14 is a similarly shaped member 23 slwhtly 7 rests upon the conical portion 16 of the member 14. The conical portion 25 of the member 23 is provided with three open slots 26, which, when the sleeve is in one position, will register with the open or upwardly ex 1 tending portions of the bayonet slots 18, but when the member 23 is turned, the conical portion of the latter locks the lugs 22 of the mantle-supporting frame in place and at the same time covers the open portions of the slots 18 so as to prevent the escape of gas through the same.

Supported upon the shoulders formed by the upper ends of the funnel-shaped members l4 and 23, is a globe support-ing member 27 having a centrally located and upwardly extending sleeve-like flange 28 which is adapted to be slipped over the tube and to engage the same with a close but sliding fit, and having also a dome-shaped portion consisting of a convex top 29 provided with suitable openings 30 for the escape of the heated air and having inwardly extending screws 32 which are designed to engage and support the globe in the usual manner.

Resting upon the globe-supporting member 27 is a so-called canopy for the protection of the ceiling, consisting of two parts, namely, a heat deflecting member 34 and a dome 35. The member 34 has a contracted lower portion, cylindrical in shape, designed to be slipped over the upper cylindrical portion 28 of the globe-supporting member 27 and to fit nicely about the same, and an outwardly flaring concave upper portion, on the top of which the dome 35 rests, the latter having a centrally located opening through which the tube 10 extends.

The funnel-shaped members 14 and 23, the globe supporting member 24, and the members 34 and 35 of the canopy are each in one piece and are preferably formed of sheet metal by stamping or spinning operations, so that in the construction of these parts there are no parts or ends united by solder, brazing or any other means.

The purpose of the flaring orifice at the lower end of the tube 10 is to permit the gas to spread outward against the body or cylindrical portion of the mantle instead of being directed downward in the direction of the length of the tube to the bottom of the mantle. This spreading action of the gas is greatly augmented by the transverse pm 17 which extends across the tube centrally thereof a shortdistance above the conical or flaring portion of the orifice, the pin serving to divide the gas, so to'speak, and to cause it to pass outwardly along the conical wall as well as in a downward direction. The result of this construction is that all portions of the mantle glow and become highly luminous causing the lamp to have a greater efliciency than those in use at the present time.

It will be apparent that the parts-of the burner can be very easily assembled or taken apart, since the parts can he slipped onto the tube 10 one after another and are supported on one another without the necessity of any special uniting means with the exception of the transverse pin 17.

It is to be noted that in the burner construction which I have shown and described above as well as in the construction of the individual parts, no brazing, soldering or the use of cooperating screw threaded portions are required, with the exception of the threaded connection between the upper end of the'tube and the valve 11. Consequently the burner has no seams, joints, or connections which can be loosened or separated by the heat of the burner.
